Security tightened

Security around Westminster was tightened following the attack by Masood, who was shot dead after fatally stabbing PC Palmer as he guarded Carriage Gate.

A review of security at the perimeter of the parliamentary estate was ordered by Commons Speaker John Bercow following the incident.

The use of armed officers and physical barriers have become more visible, while a permanent barrier has been erected to protect pedestrians on Westminster Bridge, where Masood murdered five people and injured more than 50 others by mounting the pavement in a car.
